Introduction
This chapter describes how you can quickly and easily establish S7-400
connections to sensors and actuators.
Wiring with Front Connectors
You can use front connectors to wire the S7-400. The connection between the
signal modules of your S7-400 and the sensors and actuators of your plant is
performed in two steps:
1. Wire the front connectors, insert the cables to and from the sensors/actuators
into the front connectors.
2. Mount the front connectors
